Thank you for your query. I understand your concern.
It maybe related to the jaw bone or the temperomandibular joint.
Kindly do an Xray of the area and consult an orthopedic surgeon for advice.
It can also be related to salivary gland
blockage specially the parotid gland
.If the X ray
is normal an ultrasound
of the local area could help.
It is too early to think of cancer.
problems do not cause symptoms like this.
Consult your doctor if the problem persists.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
